运动目标识别与跟踪仿真系统的基本技术问题

摘要

Concept, composing and key technology problems on the recognition and tracking simulation system of moving object are discussed. Television imaging simulation is the core of the system. In order to provide more better realism, effects of sun lighting and sky environment lightings on the moving object' s luminance are analyzed. The defocusing effect and the atmosphere turbulence effect of long distance transfer process on the target' s TV imaging are realized. Besides, the simulation met hod of delay of TV image processing on tracking is proposed. These contents are helpful to the research on the tracking system of moving object.%分析了运动目标识别与跟踪仿真系统的概念、组成及基本技术问题,并指出电视成像仿真是系统的关键.为提高电视成像仿真的数值模拟逼真度,必须在OpenGL、OSG等三维场景建模软件中考虑太阳光、天空环境光对目标亮度的作用,电视光学系统的离焦、长距离的大气传输过程中湍流对电视上目标成像的影响也不可忽略.对电视图像处理延迟对跟踪过程的影响提出了仿真方法,这些内容对研究运动目标跟踪系统是有益的.
